Answer:
a = r√(w⁴ + (alpha)²)
Explanation:
let w be the magnitude of angular velocity
r = radius
v = velocity = wr
angular acceleration, ā = v²/r = (wr)²/r = w²r
Also,
â = dv/dt = rdw/dt
given : alpha = dw/dt
hence, â = (alpha)r
the resultant acceleration, a, by Pythagoras is given as
a = √( â² + ā²) = √(r²w⁴ + r²(alpha)²)
simplifying,
a = √r²(w⁴ + (alpha)²)
a = r√(w⁴ + (alpha)²)
Answer:
condensation, precipitation, evaporation, transpiration
Explanation:
condensation is when gas condenses into liquid, precipitation is when water comes from the sky like in rain, evaporation is when water is converted from liquid to gas, transpiration is when water is evaporated from leaves.
Tennis is many different things to many different people. That's a big part of the reason why you hear so much about it, it gets on TV, and the people who are really good at it get a lot of money for running around in their shorts while they play it on TV.
To people who hate tennis but have been told by their doctors that they'll shrivel up and die if they don't immediately take up a high intensity physically-demanding sport, tennis could reasonably be classified as an exercise program.
When that happens, the best answer from the choices provided would be the upper-case ' T ' for ' True ' .
According to one source, the answer is "Grab and pull forward and backwards lengthwise.". When executed, this creates longitudinal waves which can be observed as compression waves. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
